Characteristics:

The body length may reach 2.5 cm, but a length of 1 cm is common. The cerata are often white and may work as camouflage among the eggs of other nudibranchs. Other color variations may occur, depending on the kind of food available. The body is translucent white. The white tipped rhinophores are brown at the base.

Habitat:

This rarely encountered species feeds on eggs from other nudibranchs and can be found wherever other species appear. Few registrations are deeper than 20 meters.

Distribution:

There are registrations along the coasts of Europe, from Murmansk to North-West Africa, including the Canary Islands.
